Very soon I will be building my very first PC! The only problem is I don't have build, so I thought I would ask. I am looking for something that can run most games (DayZ, Ark: Survival Evolved, CS:GO) at an average fps and that is somewhat easy to upgrade later on. Now I will need an operating system, I prefer Windows 7 (please include in build). My budget is $500 but I can stretch it to $550 if needed. So that's about it, if you would like to tell me some tips/guides for putting it together I'd appreciate it!
